Across
- 2. structural protein that anchors actin
- 4. branched and involuntary type of striated muscle
- 7. carries AP inside muscle fiber to the myofibrils
- 8. fixation of the cross bridge cycle due to lack of ATP
- 13. a common cholinesterase inhibitor
- 14. backbone of actin filament that binds myosin
- 15. composed of skeletal and cardiac muscle
- 17. forms pores into knob that allows Ca to flood in
- 18. autoimmune attack on nicotinic ACh receptors causing muscle weakness
- 23. a filamentous protein
- 24. binds to nicotinic ACh receptors blocking ACh and causing paralysis
Down
- 1. adding more motor units until desired contraction is reached
- 3. net like structure that releases Ca in skeletal muscle needed for contration
- 5. Voltage sensitive proteins in T-tubules that mechanically open Ca channels
- 6. motor neuron and all of the fibers that it innervates
- 7. controls binding of myosin via Ca
- 9. holds myosin in register
- 10. blocks docking or fusion of ACh vesicles causing paralysis
- 11. where actin and myosin overlap
- 12. middle part of myosin that doesnt overlap with actin
- 16. a protein in the SR that binds 43 Ca moderately
- 19. end parts of actin where it doesnt overlap with myosin
- 20. mediate the release of Ca in SR
- 21. the type of striated muscle that is voluntary
- 22. contractile unit that spans from z line to z line
